【発明の名称】円形ワ-クの研削装置
Document Type and Number:
Japanese Patent JP3325854
Kind Code:
B2
Abstract:
A grinding apparatus uses an inner diameter grinding wheel (4) to grind a doughnut-shaped workpiece (12), and comprising: an axle support cylinder (5) for support a sleeve-shaped grinding wheel axle (6), mounted on which is the grinding wheel (4) having annular grinding grooves (13) in its inner peripheral surface. The axle (6) is rotatably mounted in the cylinder (5) to vertically pass therethrough and has an upper surface on which the grinding wheel (4) is fixedly mounted; a means for rotatably driving the axle (6); and, a workpiece axle support sleeve (18) provided with a lower workpiece clamp (20) in its upper end, to which the workpiece (12) is attracted by the suction. The sleeve (18) is freely passed through the axle (6). The cylinder (5) and/or the sleeve (18) are capable of moving vertically and horizontally. The apparatus is improved in grinding efficiency to reduce grinding costs.
